Randomized Controlled Trial Comparative Study Clinical TrialA randomized prospective clinical trial comparing laser subepithelial keratomileusis and photorefractive keratectomy.
To compare laser subepithelial keratomileusis (LASEK) and photorefractive keratectomy (PRK) in different eyes of the same subjects for subjective pain level, visual acuity, and corneal epithelial healing. ⋯ Laser subepithelial keratomileusis and PRK have similar postoperative pain thresholds and visual acuity recordings. However, the epithelial healing pattern for LASEK and PRK differs. No additional clinical benefit is seen from the LASEK procedure relative to the PRK procedure.
